I have an 03 sedan with 124k.
And it runs strong and turns on like it was new. So I'm thankful for that!
As for mileage, now a days I get about the same. About 230-245. Of course I know I could get better but my right foot can get a little carried away, especially on long boring hwy driving

Oh and I got new tires that are traction bias (as opposed to mileage tires) this last May. So that took a bite out of my mileage. But I knew it would. I rather have traction and stopping power than better mpgs and crashing into people or things. I've slid into the intersection too many times or come close. No thanks!
